Intermittent Hypoxic Exposure

IHE stands for Intermittent Hypoxic Exposure, a technique of breathing short bursts of mountain air through a mask, alternated with normal air. IHE is the quickest way to adapt to low oxygen.

No exercise required

A course of IHE is enough to improve your physiology in order to obtain the competitive advantage in sport, pre-acclimatise for a high altitude trip, or to improve your general wellbeing. Independent scientific research suggests IHE provides an up-regulation in adaptive hormones and improvements in mitochondrial function (the powerhouses inside our cells). This make each of our cells more responsive to changes in oxygen levels.

We recommend using IHE as close to your event as possible.

You can rent an IHE system for home use or come to our centres to conduct a session with a member of staff.


Benefits for Mountaineering

To climb a mountain you need a certain level of fitness, but fitness alone will not get you to the top. Your body needs to acclimatise to the reduced oxygen found at altitude. The only way you can do that is to spend extra days at altitude or start the acclimatisation process before you go.

• Use IHE to assess how you cope at altitude.
• Pre-acclimatise up to altitudes of 6,500m.

IHE stimulates the physiological adaptations necessary to ensure an increased oxygen carrying capacity within the body, ensuring your trip to altitude is safer and more enjoyable. We want you to enjoy the view from the top.


Benefits for sport

Oxygen is the limiting factor in sports performance. When insufficient oxygen is delivered to the muscles fatigue sets in. Athletes are using IHE to:

• Stimulate the adaptive process to increase 
 the body’s oxygen carrying capacity
• Increase endurance, speed and power
• Prepare for races at altitude
• Maintain fitness whilst injured
• Recover from chronic fatigue and 


Benefits for health

Oxygen is essential for human life. IHE trains your system to increase the carrying capacity of oxygen within your body. By training your system with rhythmical cycles of hypoxic air you are able to enhance all areas of the human system:

• Improve breathing efficiency
• Improve metabolism
• Reduce stress levels
• Increase weight loss
• Improve the antioxidant and immune 
• Improve overall health and wellbeing
